Infant CPR USE to train to do a sweep check of the mouth, it no longer does because it causes the food to get shoved further down, blocking the airway more.
Flip him, head down on your forearm and tap between his shoulder blades.

This is the exact reason I cut everything small, from fruit to pizza, etc... You just never know when they will choke. Their airways are small and though I know infant CPR, I'd rather not have to use it.

Exactly, when I did my CPR training, we were specifically told to *only* do a finger sweep if we could see the food, and there was a big enough piece to "hook and pull" And to *only* do it if the 1st couple of taps/hits don't dislodge it.
